Gavrilo Princip, the assassin who killed Archduke Franz Ferdinand of Austria in 1914, was arrested immediately after the assassination. He was only 19 years old at the time. Princip was tried and convicted of the assassination, but due to his young age, he was sentenced to 20 years in prison rather than facing the death penalty. He died in prison in 1918, just a few months before the end of World War I. **

During the First World War, Gavrilo Princip was arrested by the Austro-Hungarian authorities for his role in the assassination of Archduke Franz Ferdinand. He was sentenced to 20 years in prison but died of tuberculosis in 1918, just three years into his sentence. Despite his actions sparking the war, Princip did not live to see the end of the conflict. **

Gavrilo Princip killed Franz Ferdinand and his wife, Sophie, as an act of political terrorism. He was a member of the nationalist group known as the Black Hand, which sought to achieve independence for South Slavic peoples from the Austro-Hungarian Empire. The assassination was intended to spark a chain of events that would lead to the liberation of the South Slavic territories from Austro-Hungarian rule. Ultimately, the assassination of Franz Ferdinand and his wife was a catalyst for the outbreak of World War I. **

Gavrilo Princip, the assassin of Archduke Franz Ferdinand, is not solely to blame for the outbreak of the First World War. While his actions did trigger a chain of events that led to the war, there were underlying political, economic, and military tensions among the major European powers that were already pushing them towards conflict. The assassination provided the spark that ignited these tensions, but it was not the sole cause of the war. The complex web of alliances, imperial ambitions, and long-standing rivalries among the European powers all played significant roles in the outbreak of the war. **

A gas heater uses a spark to ignite the gas and create a flame. Once the gas is ignited, it continues to burn and produce heat without the need for a continuous spark. Therefore, after the initial spark, there is no need for it to remain lit as long as the gas is burning. This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **

To heat a plate over a candle flame, you can hold the plate above the flame at a safe distance to avoid direct contact with the flame. Move the plate back and forth over the flame to evenly distribute the heat. Be cautious not to hold the plate too close to the flame to prevent it from getting too hot or potentially breaking. **

No, ember is not hotter than fire. Ember is the glowing remains of a fire that has started to die down, whereas fire is the active, burning flames produced by a combustion reaction. Fire typically burns at a higher temperature than ember, as it is actively consuming fuel and releasing heat and light. **

An ember tetra is a small freshwater fish that is popular in the aquarium hobby. It is known for its vibrant red and orange coloration, resembling the glowing embers of a fire, hence its name. Ember tetras are peaceful and social fish that do well in community aquariums with other small, non-aggressive fish. They are relatively easy to care for and are a great choice for beginner fish keepers. **
